United Nations Ambassador Nikki Haley said the United States on Monday will impose more economic sanctions against Russia after its repeated support of Syrian President Bashar Assad and his apparent use of chemical weapons on his own people.
Speaking on CBS News' "Face the Nation" Sunday, Haley said U.S. Treasury Secretary Steven Mnuchin will make the announcement about the country's intent to target companies that deal with equipment related to Assad and Syria's chemical weapons.
"I think everyone knows that we sent a strong message and our hope is that they listen to it," Haley said.
The ambassador's comments come days after the United States launched a joint missile airstrike with the U.K. and France. Haley, a former South Carolina governor, said the time for negotiation had run out when the United States decided to launch the missile strike in Syria.
She defended the military move as a strategic one in which storage and research facilities that Haley described as "the heart" of their chemical weapons program were the targets — not civilians.
"This was very strong attack on the chemical weapons program," she said. "We were not looking for war. That's the last thing the president wanted was war. We were not looking to kill people. That was not something that in our American values we would want to do."
Haley then added, "This was not muscle flexing. We set their chemical weapons program back years."
President Donald Trump on Saturday described the U.S.-led allied attack as "Mission accomplished."
While he declared success, the Pentagon said the pummeling of three chemical-related facilities left enough others intact to enable the Assad government to use banned weapons against civilians if it chooses.
Assad has denied using chemical weapons.
